How common is OCD?

  • Our best estimates are that about 1 in 100 adults—or between 2–3 million adults in the United States—currently have OCD. This is roughly the same number of people living in the city of Houston, Texas.
  • Lifetime estimates (the number of individuals that develop OCD over the course of their lifetime) are that about 1 in 50 adults—or 4–6 million adults in the United States—have OCD.
  • There are also at least 1 in 200—or 500,000—kids and teens that have OCD. This is about the same number of kids who have diabetes.
  • This means four or five kids with OCD are likely to be enrolled in any average sized elementary school. In a medium to large high school, there could be 20 studens struggling with the challenges caused by OCD.
  • OCD affects men, women and children of all races and backgrounds equally.
